I do have her, and I have her raised for farming (Lv80 and third skill at 9/10), but she just seems really, really underwhelming in that role. While the writeup on her page keeps alluding to teams with debuff removal centered around her being (somehow) viable, I can’t really comment on that, since I never used her in that role (as I, frankly, have better servants for serving the damage dealer role in a team like that), but as an actual farming servant, she seems to be greatly outclassed by the likes of Arash, Spartacus and Bunyan, who are all free servants.
I mean, with full support, my Fran deals about 45k damage per enemy, while Spartacus does close to 70k. Granted, both of these numbers are a gross overkill for daily farming, but the thing is, unlike Fran, Spartacus is free, requires way less investment (read: those damn bones), doesn’t get stunned after NP, and his main steroid is stronger than hers and doesn’t have a demerit, with the only part where Fran is superior being her star gen on her NP. Oh, and aesthetics, but I think that goes without saying.
So, just to reiterate: Fran, as a premium berserker, has multiple demerits, including a self-stun, has no hard-defense or sustain, no battery, no team support, and her NP is weaker than a free 1* berserker’s… yet she is somehow a tier 2 servant? What exactly am I missing here?
